  • How secure is a PostgreSQL database if my server is stolen?

    - by orokusaki
    If I have a server with a database if top secret data in PostgreSQL and my password is practically impossible to crack (128 character string of all sorts of weird chars, generated by hand). The server password is also uncrackable in theory (basically, ignore the possibility of a password crack on the DB). Aside from a password crack, how easy is it to get the data out of this database? Assumptions: Only the DB exists on the server. There is no password in a PHP script or anything like that The person who has the server is a computer / DB / hard-drive recovery expert I'm not using any hard-drive encryption or anything out of the norm for protection I'm trying to understand the risks involved with somebody gaining physical access to my server's hard-drives.

  • Is it safe to assert a functions return type?

    - by wb
    This question is related to this question. I have several models stored in a collection. I loop through the collection and validate each field. Based on the input, a field can either be successful, have an error or a warning. Is it safe to unit test each decorator and assert that the type of object returned is what you would expect based on the given input? I could perhaps see this being an issue for a language with function return types since my validation function can return one of 3 types. This is the code I'm fiddling with: <!-- #include file = "../lib/Collection.asp" --> <style type="text/css"> td { padding: 4px; } td.error { background: #F00F00; } td.warning { background: #FC0; } </style> <% Class UserModel Private m_Name Private m_Age Private m_Height Public Property Let Name(value) m_Name = value End Property Public Property Get Name() Name = m_Name End Property Public Property Let Age(value) m_Age = value End Property Public Property Get Age() Age = m_Age End Property Public Property Let Height(value) m_Height = value End Property Public Property Get Height() Height = m_Height End Property End Class Class NameValidation Private m_Name Public Function Init(name) m_Name = name End Function Public Function Validate() Dim validationObject If Len(m_Name) < 5 Then Set validationObject = New ValidationError Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Name Set Validate = validationObject End Function End Class Class AgeValidation Private m_Age Public Function Init(age) m_Age = age End Function Public Function Validate() Dim validationObject If m_Age < 18 Then Set validationObject = New ValidationError ElseIf m_Age = 18 Then Set validationObject = New ValidationWarning Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Age Set Validate = validationObject End Function End Class Class HeightValidation Private m_Height Public Function Init(height) m_Height = height End Function Public Function Validate() Dim validationObject If m_Height > 400 Then Set validationObject = New ValidationError ElseIf m_Height = 324 Then Set validationObject = New ValidationWarning Else Set validationObject = New ValidationSuccess End If validationObject.CellValue = m_Height Set Validate = validationObject End Function End Class Class ValidationError Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "error" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ValidationWarning Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "warning" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ValidationSuccess Private m_CSSClass Private m_CellValue Public Property Get CSSClass() CSSClass = "" End Property Public Property Let CellValue(value) m_CellValue = value End Property Public Property Get CellValue() CellValue = m_CellValue End Property End Class Class ModelValidator Public Function ValidateModel(model) Dim modelValidation : Set modelValidation = New CollectionClass ' Validate name Dim name : Set name = New NameValidation name.Init model.Name modelValidation.Add name ' Validate age Dim age : Set age = New AgeValidation age.Init model.Age modelValidation.Add age ' Validate height Dim height : Set height = New HeightValidation height.Init model.Height modelValidation.Add height Dim validatedProperties : Set validatedProperties = New CollectionClass Dim modelVal For Each modelVal In modelValidation.Items() validatedProperties.Add modelVal.Validate() Next Set ValidateModel = validatedProperties End Function End Class Dim modelCollection : Set modelCollection = New CollectionClass Dim user1 : Set user1 = New UserModel user1.Name = "Mike" user1.Age = 12 user1.Height = 32 modelCollection.Add user1 Dim user2 : Set user2 = New UserModel user2.Name = "Phil" user2.Age = 18 user2.Height = 432 modelCollection.Add user2 Dim user3 : Set user3 = New UserModel user3.Name = "Michele" user3.Age = 32 user3.Height = 324 modelCollection.Add user3 ' Validate all models in the collection Dim modelValue Dim validatedModels : Set validatedModels = New CollectionClass For Each modelValue In modelCollection.Items() Dim objModelValidator : Set objModelValidator = New ModelValidator validatedModels.Add objModelValidator.ValidateModel(modelValue) Next %> <table> <tr> <td>Name</td> <td>Age</td> <td>Height</td> </tr> <% Dim r, c For Each r In validatedModels.Items() %><tr><% For Each c In r.Items() %><td class="<%= c.CSSClass %>"><%= c.CellValue %></td><% Next %></tr><% Next %> </table> Thank you.

  • Dell V105 printer and OS X 10.6

    - by James
    I am trying to get a Dell V105 printer to work with my iMac. It is running 10.6 and I have installed all the drivers on the Snow Leopard disk. I believe there is no official Dell driver but I have also heard the Dell printers are made by third parties that may sell the same printer under different names. There a quite a few Lexmark models that seem to look very similar and I have tried setting the driver to the 2600 series that looks very similar but that has not enabled me to print. Although it claims to give me the supply levels correctly. Can anyone help? Thanks for your time

  • How do I pick a motherboard?

    - by EpsilonVector
    When building your own computer one part was always a mystery to me: the motherboard. Picking a CPU/GPU/memory is easy- you just figure out where the various chips are in the low end to high end scale, do a little market research on what current games demand, and pick the parts from their respective continuums of low-to-high-end models. A mother board is more complicated though. Its features are not as obvious as "this motherboard is faster than that motherboard". Now you need to deal with part compatibilities, bus speeds, maybe power management stuff, etc. I'm interested in a short guide for selecting a motherboard, especially- what pitfalls to avoid (for example, can bus speed become a bottleneck?). To clarify: I'm not looking for motherboard recommendations. I'm looking for guidance regarding how to evaluate the fitness of a motherboard given the rest of the computer parts.

  • MVC design in Cocoa - are all 3 always necessary? Also: naming conventions, where to put Controller

    - by Nektarios
    I'm new to MVC although I've read a lot of papers and information on the web. I know it's somewhat ambiguous and there are many different interpretations of MVC patterns.. but the differences seem somewhat minimal My main question is - are M, V, and C always going to be necessary to be doing this right? I haven't seen anyone address this in anything I've read. Examples (I'm working in Cocoa/Obj-c although that shouldn't much matter).. 1) If I have a simple image on my GUI, or a text entry field that is just for a user's convenience and isn't saved or modified, these both would be V (view) but there's no M (no data and no domain processing going on), and no C to bridge them. So I just have some aspects that are "V" - seems fine 2) I have 2 different and visible windows that each have a button on them labeled as "ACTIVATE FOO" - when a user clicks the button on either, both buttons press in and change to say "DEACTIVATE FOO" and a third window appears with label "FOO". Clicking the button again will change the button on both windows to "ACTIVATE FOO" and will remove the third "FOO" window. In this case, my V consists of the buttons on both windows, and I guess also the third window (maybe all 3 windows). I definitely have a C, my Controller object will know about these buttons and windows and will get their clicks and hold generic states regarding windows and buttons. However, whether I have 1 button or 10 button, my window is called "FOO" or my window is called "BAR", this doesn't matter. There's no domain knowledge or data here - just control of views. So in this example, I really have "V" and "C" but no "M" - is that ok? 3) Final example, which I am running in to the most. I have a text entry field as my View. When I enter text in this, say a number representing gravity, I keep it in a Model that may do things like compute physics of a ball while taking in to account my gravity parameter. Here I have a V and an M, but I don't understand why I would need to add a C - a controller would just accept the signals from the View and pass it along to the Model, and vice versa. Being as the C is just a pure passthrough, it's really "junk" code and isn't making things any more reusable in my opinion. In most situations, when something changes I will need to change the C and M both in nearly identical ways. I realize it's probably an MVC beginner's mistake to think most situations call for only V and M.. leads me in to next subject 4) In Cocoa / Xcode / IB, I guess my Controllers should always be an instantiated object in IB? That is, I lay all of my "V" components in IB, and for each collection of View objects (things that are related) I should have an instantiated Controller? And then perhaps my Models should NOT be found in IB, and instead only found as classes in Xcode that tie in with Controller code found there. Is this accurate? This could explain why you'd have a Controller that is not really adding value - because you are keeping consistent.. 5) What about naming these things - for my above example about FOO / BAR maybe something that ends in Controller would be the C, like FancyWindowOpeningController, etc? And for models - should I suffix them with like GravityBallPhysicsModel etc, or should I just name those whatever I like? I haven't seen enough code to know what's out there in the wild and I want to get on the right track early on Thank you in advance for setting me straight or letting me know I'm on the right track. I feel like I'm starting to get it and most of what I say here makes sense, but validation of my guessing would help me feel confident..

  • SQL Server Express 2008 Stored Procedure execution time spikes periodically

    - by user156241
    I have a big stored procedure on a SQL Server 2008 Express SP2 database that gets run about every 200 ms. Normal execution time is about 50ms. What I am seeing is large inconsistencies in this run time. It will execute for while, say 50-100 times at 40-60ms which is expected, then seemingly at random the same stored procedure will take way longer, say 900ms or 1.5 seconds to run. Sometimes more than one call of the same procedure in a row will take longer too. It appears that something is causing sql server to slow down dramatically every minute or so, but I can't figure out what. There is no timing pattern between the occurences. I have the same setup on two different computers, one of which is a clean XP Pro load with no virus checking and nothing installed except SQL server. Also, The recovery options for all the databases are set to "Simple".

  • Magento - Data is not inserted into database, but the id is autoincremented

    - by Joseph
    I am working on a new payment module for Magento and have come across an issue that I cannot explain. The following code that runs after the credit card is verified: $table_prefix = Mage::getConfig()->getTablePrefix(); $tableName = $table_prefix.'authorizecim_magento_id_link'; $resource = Mage::getSingleton('core/resource'); $writeconnection = $resource->getConnection('core_write'); $acPI = $this->_an_customerProfileId; $acAI = $this->_an_customerAddressId; $acPPI = $this->_an_customerPaymentProfileId; $sql = "insert into {$tableName} values ('', '$customerId', '$acPI', '$acPI', '3')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acAI', '2')"; $writeconnection->query($sql); $sql = "insert into {$tableName} (magCID, anCID, anOID, anObjectType) values ('$customerId', '$acPI', '$acPPI', '1')"; $writeconnection->query($sql); I have verified using Firebug and FirePHP that the SQL queries are syntactically correct and no errors are returned. The odd thing here is that I have checked the database, and the autoincrement value is incremented on every run of the code. However, no rows are inserted in the database. I have verified this by adding a die(); statement directly after the first write. Any ideas why this would be occuring? The relative portion of the config.xml is this: <config> <global> <models> <authorizecim> <class>CPAP_AuthorizeCim_Model</class> </authorizecim> <authorizecim_mysql4> <class>CPAP_AuthorizeCim_Model_Mysql4</class> <entities> <anlink> <table>authorizecim_magento_id_link</table> </anlink> </entities> <entities> <antypes> <table>authorizecim_magento_types</table> </antypes> </entities> </authorizecim_mysql4> </models> <resources> <authorizecim_setup> <setup> <module>CPAP_AuthorizeCim</module> <class>CPAP_AuthorizeCim_Model_Resource_Mysql4_Setup</class> </setup> <connection> <use>core_setup</use> </connection> </authorizecim_setup> <authorizecim_write> <connection> <use>core_write</use> </connection> </authorizecim_write> <authorizecim_read> <connection> <use>core_read</use> </connection> </authorizecim_read> </resources> </global> </config>

  • Intel T5600 to upgrade T5250

    - by galets
    I want to upgrade my laptop which has T5250 CPU with a T5600 CPU to support virtualization. I ordered T5600 on ebay, but it didn't fit. It says T5250 supports PPGA478 socket, so I assume that is what I have. T5600 says supports "PBGA479, PPGA478". Since T5600 didn't fit as a replacement, I assume it means there are 2 models of T5600, one supports PBGA479, another one supports PPGA478, and not like I thought - one CPU supports both. Is that a correct statement? Does anybody know if it's even possible to do such an upgrade, or I'm wasting time?

  • How to check the OS is running on bare metal and not in virtualized environment created by BIOS?

    - by Arkadi Shishlov
    Is there any software available as a Linux, *BSD, or Windows program or boot-image to check (or guess with good probability) the environment an operating system is loaded onto is genuine bare metal and not already virtualized? Given recent information from various sources, including supposed to be E.Snowden leaks, I'm curious about the security of my PC-s, even about those that don't have on-board BMC. How it could be possible and why? See for example Blue Pill, and a number of papers. With a little assistance from network card firmware, which is also loadable on popular card models, such hypervisor could easily spy on me resulting in PGP, Tor, etc. exercises futile.

  • Different versions of 2.5" drives? Unscreawing Intel 320 for slimmer drive to fit newer thinkpads?

    - by hhh
    My x60s laptops come with about 1-2mm heigher 2.5" HDD than newer x220 models. This is totally stupid when one would like to reuse the old drive in the newer laptops. I bought newer 2.5" 320 Intel SSDs and they seem to have such 1-2mm gap to unscrew but I am unsure whether it is meant for opening. Could someone instruct what to do here? Look the manufacturer has started changing the old good 2.5" drives into slightly different versions, now it means slow compability issues to fix or totally new 2.5" drives. Ideas how to proceed? Unscrewing newer 320 drives or are some other versions of 2.5" drives meant for x220? Does there exist some sort of racks to get drives working between different comps? Perhaps booting from laplink is currently the easiest solution to get things working when changing harddrives between comps?

  • Paperclip: "missing" image when uses has_one

    - by EricR
    I'm working on a website that allows people who run bed and breakfast businesses to post their accommodations. I would like to require that they include a "profile image" of the accommodation when they post it, but I also want to give them the option to add more images later (this will be developed after). I thought the best thing to do would be to use the Paperclip gem and have a Accommodation and a Photo in my application, the later belonging to the first as an association. A new Photo record is created when they create an Accommodation. It has both id and accommodation_id attributes. However, the image is never uploaded and none of the Paperclip attributes get set (image_file_name: nil, image_content_type: nil, image_file_size: nil), so I get Paperclip's "missing" photo. Any ideas on this one? It's been keeping me stuck for a few days now. Accommodation models/accommodation.rb class Accommodation < ActiveRecord::Base validates_presence_of :title, :description, :photo, :thing, :location attr_accessible :title, :description, :thing, :borough, :location, :spaces, :price has_one :photo end controllers/accommodation_controller.erb class AccommodationsController < ApplicationController before_filter :login_required, :only => {:new, :edit} uses_tiny_mce ( :options => { :theme => 'advanced', :theme_advanced_toolbar_location => 'top', :theme_advanced_toolbar_align => 'left', :theme_advanced_buttons1 => 'bold,italic,underline,bullist,numlist,separator,undo,redo', :theme_advanced_buttons2 => '', :theme_advanced_buttons3 => '' }) def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) end def new @accommodation = Accommodation.new end def create @accommodation = Accommodation.new(params[:accommodation]) @accommodation.photo = Photo.new(params[:photo]) @accommodation.user_id = current_user.id if @accommodation.save flash[:notice] = "Successfully created your accommodation." render :action => 'show' else render :action => 'new' end end def edit @accommodation = Accommodation.find(params[:id]) end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." render :action => 'show' else render :action => 'edit' end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end private def check_owner end end views/accommodations/_form.html.erb <%= form_for @accommodation, :html => {:multipart => true} do |f| %> <%= f.error_messages %> <p> Title<br /> <%= f.text_field :title, :size => 60 %> </p> <p> Description<br /> <%= f.text_area :description, :rows => 17, :cols => 75, :class => "mceEditor" %> </p> <p> Photo<br /> <%= f.file_field :photo %> </p> [... snip ...] <p><%= f.submit %></p> <% end %> Photo The controller and views are still the same as when Rails generated them. models/photo.erb class Photo < ActiveRecord::Base attr_accessible :image_file_name, :image_content_type, :image_file_size belongs_to :accommodation has_attached_file :image, :styles => { :thumb=> "100x100#", :small => "150x150>" } end

  • Ranking tables from Excel data

    - by Joe
    Hi all (asking here because this meta question told me to). I have some data in an excel spreadsheet here. It's no more than a table with about five columns. Year Purchased Manufacturer Model Num Unit Price Total Price 2007 SMARTBOX FuturePad XP 1 £2,915.00 £2,915.00 2007 Attainment Company Inc Go Talk 9+ 1 £104.00 £104.00 2007 Attainment Company Inc Go Talk 20+ 1 £114.00 £114.00 I'd like to be able to build a 'top ten' of either manufacturers or models (and I'd like to be able to do it by either most mentioned, most sales, or highest value of sales) - but I've got no idea what the best method is in excel. Any suggestions...? The ideal output might be a set of sells that says something like Company Units A 5342 B 232 C 2 D 1

  • When saving a model with has_one or has_many associations, which side of the association is saved fi

    - by SeeBees
    I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid > from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/validations.rb:1090:in > `save_without_dirty!' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/dirty.rb:87:in `save_without_transactions!' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:200:in > `save!' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/connection_adapters/abstract/database_statements.rb:136:in > `transaction' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:182:in > `transaction' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:200:in > `save!' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:208:in > `rollback_active_record_state!' from > /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:200:in > `save!' from (irb):14 I figured out that when team.save! is called, it first calls player.save!. player needs to validate the presence of the id of the associated team. But at the time player.save! is called, team hasn't been saved yet, and therefore, team_id doesn't yet exist for player. This fails the player's validation, so the error occurs. But on the other hand, team is saved before coach.save!, otherwise the first example will get the same error as the second one. So I've concluded that when a has_many bs, a.save! will save bs prior to a. When a has_one b, a.save! will save a prior to b. If I am right, why is this the case? It doesn't seem logical to me. Why do has_one and has_many association have different order in saving? Any ideas? And is there any way I can change the order? Say I want to have the same saving order for both has_one and has_many. Thanks.

  • Is it immoral to put a captcha on a login form?

    - by azkotoki
    In a recent project I put a captcha test on a login form, in order to stop possible brute force attacks. The immediate reaction of other coworkers was a request to remove it, saying that it was inapropiate for that purpose, and that it was quite exotic to see a captcha in that place. I've seen captcha images on signup, contact, password recovery forms, etc. So I personally don't see inapropiate to put a captcha also on a place like that. Well, it obviously burns down usability a little bit, but it's a matter of time and getting used to it. With the lack of a captcha test, one would have to put some sort of blacklist / account locking mechanism, which also has some drawbacks. Is it a good choice for you? Am I getting somewhat captcha-aholic and need some sort of group therapy? Thanks in advance.

  • Are some DSL modems cheaper to operate than others? (power usage question)

    I recently have started using a Motorola 2210 in conjunction with AT&T's DSL service in the Silicon Valley area. That gadget runs hot to the touch! Which means... I assume it is gobbling lots of electricity even when I am not using it. Has anyone studied this subject in a rigorous way? Which leads to the question... if the 2210 is very energy inefficient are some DSL modem models cheaper to operate than others? -SetJmp

  • Catch unhandled exception of invisible thread

    - by user346804
    In my C++ application i use an activeX component that runs its own thread (or several I don't know). Sometimes this components throws exceptions. I would like to catch these exceptions and do recovery instead of my entire application crashing. But since I don't have access to its source code or thread I am unsure how it would be done. The only solution I can think of is to run it in its own process. Using something like CreateProcess and then CreateRemoteThread, unsure how it could be implemented. Any suggestion on how to go about solving this?

  • how to get memory dump after blue screen

    - by user464164
    I'm getting a lovely BSOD on bootup (STOP: 0x0000007E) from a driver I'm writing, and would like to load up the memory dump for analysis. However, it's not getting dumped anywhere. Everything is setup correctly in the Startup and Recovery settings, but I get no dump file, and nothing in the event log stating a dump has taken place. It looks like a dump is not even occurring... I know the exact line of code causing it (a call to IoAttachDevice()), but am not sure why, and would like to view the DbgPrint output to see where exactly it's failing. Could Windows possibly be crashing before the dumping functionality is set up? If so, how do I get access to the state of the machine when the failure occurs? UPDATE: Other possibly useful information: I'm running Windows XP through VirtualBox on a Linux host.

  • Does the .NET Framework need to be reoptimized after upgrading to a new CPU microarchitecture?

    - by Louis
    I believe that the .NET Framework will optimize certain binaries targeting features specific to the machine it's installed on. After changing the CPU from an Intel Nehalem to a Haswell chip, should the optimization be run again manually? If so, what is the process for that? Between generations here are some notable additions: Westmere: AES instruction set Sandy Bridge: Advanced Vector Extensions Ivy Bridge: RdRand (hardware random number generator), F16C (16-bit Floating-point conversion instructions) Haswell: Haswell New Instructions (includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support) So my, albeit naive, thought process was that the optimizations could take advantage of these in general cases. For example, perhaps calls to the Random library could utilize the hardware-RNG on Ivy Bridge and later models.

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • What's exactly the nature of .Net Framework 3.5 Service Pack1?

    Hello, I did some recovery disk operations with my laptop because it became instable. Now, I'm about to re-install SQL Server 2008 Professional, but it keeps telling me that I need to install .net framework 3.5 with service pack1. What's strange is I was asked to do the same when I installed Visual Studio 2008 Professional earlier. I'd like to know: what's .Net Framework Service Pack1? is it One piece of software sitting on top of windows ? Several software having the same name so that Visual Studio has it, SQL Server also has it, and do on... And why the naming Service Pack1 behind .Net Framework? I'm really lost. Thanks for helping

    The machine will store and serve millions of small files (<15Kb each), and all those files require a total storage space of 400G Considering the exact same SATA hard drives maker and models, on the exact same environment (OS, cpu, ram, raid controller, etc...) which one of the setups bellow would be faster? A) RAID 1 with 2 drives of 2T each, making up total storage of 2T B) RAID 10 with 4 drives of 2T each, making up total storage of 4T [EDIT]: I'm aware RAID10 is faster than RAID1. The larger the disk, at least in theory, the longer will take to do seeks/writes. So, will the performance gain of RAID10 will be outweighed by the "drag" caused the larger disk area when seek/write operations happened?

  • Blurred refurbished TFT

    - by PeterMmm
    I got 3 refurbished PC+TFT 19". All TFT shows a very blurry image. I estimate the TFT's are 2-3 yrs old. The PC's running Windows7 Pro. The resolution is set to the TFT native values. It could be possible that all TFT's are broken but I have similiar models that are up to 5 yrs old, without any issue. I still think it could be a config issue but from the hardware it is possible that a TFT get broken I shows up a very blurry image. Update TFT HP 2035, grafic Intel Q35/GMA 3100, analog D-SUB connector, Manuf. date Sep 2005. Config. resolution 1600x1200, PPP 150% Without ClearType it is worst. Desktop Icon titles seems to be good and clear. But in Notepad for example the effect is that on the right of the characters is a pinky shadow.

  • Does a modern PC require a graphics card to run?

    - by ArtM
    As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days). Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present. Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my firends for a few hours/days and use it when installing the necessary software. The question is: can I boot and run the PC without problems after I install everything I need and the graphics card is removed? if a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpfull I think it's obvious, but for completeness: I mean cheap desktop components, not real servers.

  • Customer provider Password Reset client.

    - by ProfK
    I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.
